To Compare the Effects of Different Doses of Dexmedetomidine on Intrathecal Bupivacaine in Infraumbilical Surgeries: A Prospective, Randomized, Double-blind Clinical Study.

Introduction: Spinal anesthesia is preferred technique of choice in infraumbalical surgeries. Limitation of this technique is shorter duration of analgesia, so various adjuvants have been used with intrathecal bupivacaine such as fentanyl, clonidine, and dexmedetomidine. Dexmedetomidine is a highly selective alpha 2 adrenergic agonist.
